Description
Technical field
It is more particularly to a kind of to improve insulated tension pole external insulation performance the present invention relates to a kind of technical field of power equipment
Method.
Background technology
Currently used for driving, the insulation mode between the insulated tension pole and moving contact of the motion of vacuum interrupter moving contact is general
There are the insulation modes such as air insulation, oil-insulation, SF6 gas-insulateds, insulating properties respectively have quality.As air insulation volume is big, exhausted
Edge poor performance, easily influenceed to cause apparatus insulated puncture by outdoor environment；SF6 gas-insulateds may not apply to plateau, extremely tremble with fear ground
Area, insulation decline easily causes equipment explosion after the leakage of SF6 gases, and SF6 belongs to greenhouse gases, not environmentally, is not easily recycled；Oil
Insulation complex manufacturing, influenceed to easily cause oil leak by outdoor environment and apparatus insulated performance reduction is caused equipment explosion；
And insulating oil is not environmentally, is not easily recycled.Therefore a kind of method of good raising insulated tension pole external insulation performance is found, is lifting
The only way which must be passed of middle voltage electrical equipment performance.
The content of the invention
To solve the above problems, the present invention provides a kind of method for improving insulated tension pole external insulation performance.
The technical scheme is that：A kind of method for improving insulated tension pole external insulation performance, comprises the following steps
1. pole is fixed on insulating sleeve with vacuum switch tube,
2. in pole with hard silicon rubber is poured into a mould in the cavity between vacuum switch tube and insulating sleeve, the hard silicon such as stand
Cure of Rubber；
3. positioning spacer is set between the end of vacuum switch tube and insulating sleeve in pole, pole is used
Cavity closing between vacuum switch tube and insulating sleeve；
4. pole vacuum switch tube is connected with insulated tension pole component by being flexible coupling,
5. the cavity being flexible coupling, between insulated tension pole component and insulating sleeve pours into a mould soft silicon rubber；
6. after soft silicon rubber is poured by flexible sealing barrier film by lock sleeve and lock sleeve, be separately fixed at insulation draw
In bar assembly and on insulating sleeve.
The present invention is realized using following technical measures：
Pole is fixed in insulating sleeve with vacuum switch tube, one end of insulated tension pole by pole with using true
The moving contact of empty switching tube is rigidly connected, and the location of pole vacuum switch tube and insulated tension pole are divided into two
Not connected space,
Soft silicon rubber is poured into a mould around insulated tension pole, the soft silicon rubber has a good electrical insulation properties, and can be with
Connection is glued well with other materials, electricity is climbed so as to block, and plays a part of sealed insulation pull bar, so that it is no longer by the external world
The influence of environment.By being sealed by the good soft silicon rubber of electrical insulation properties around insulated tension pole, so its external form
Size by air insulation just without being considered, so that its overall dimensions is greatly reduced.
By the viscosity for adjusting soft silicon rubber so that insulated tension pole can obtain certain damped coefficient when moving, from
And good second order velocity and acceleration response curve is obtained, shock loading of the closing process to arc-chutes is reduced, is improved
The life-span of arc-chutes；Separating brake overshoot is reduced to the shock loading of mechanism, the life-span of mechanism is improved.
In order to ensure that soft silicon rubber glues connection well with insulating cylinder, insulated tension pole, insulating cylinder and insulated tension pole are used and sprayed
The process of surface treatment of sand and ball blast, makes its rough surface, be more conducive to and soft silicon rubber combination.
Use vacuum casting process when pouring into a mould soft silicon rubber, and remove moisture removal, it is ensured that it is poured be poured in after, it is whole as one
The excellent interior insulation performance of body.
